XVILLIAM GOLDSMITH, OF CENTRAL FALLS, RHODE ISLAND.

MULE-SPINNING MACHlNE.

SPECIFICATION forming part of Letters Patent No. 653,864, dated July 17, 1900.

Application filed November 6, 1899. Serial No. 735,887. (No model.)

To all whom it may concern.-

Be it known that LIVILLIAM H. GOLDSMITH, a citizen of the United States, residing at Central Falls, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Mule-Spinning Machines, of which the following is a specification.

This invention refers to an improvement in mule-spinning machines; and it consists in the peculiar and novel construction and combination of the parts whereby on the occurrence of certain abnormal conditions the driving mechanism will be automatically stopped and protected against injury, as will be more fully set forth hereinafter.

In the class of mule-spinning machines in which a quadrant provided with a segmental gear forms part of the operative mechanism the quadrant is operated by a pinion driven by a band known as the quadrant-band, extending from a drum at the driving end of the mule-head to a drum connected with the shaft of the pinion operating the quadrant. This quadrant-band requires the constant care and vigilant supervision of the attendant, because the breaking of this band is liable to cause the destruction of part of the complicated driving mechanism of the machine before the same can be stopped. In the present practice when this quadrant-band shows signs of wear and weakening it is usu-. ally removed and a new one is substituted.

The objects of this invention are to release the attendant of this care and anxiety and to prevent injury to the driving mechanism by the breaking of the quadrant-band.

Figurel is atop view of the end of the driving-head of a mule-spinning machine, showing the quadrant-band, the quadrant-pinion, and the change-lever as used in this class of mules in connection'with my improved stopmotion. Fig. 2 is a sectional view of the same. Fig. 3 is an end view; and Fig. 4 is a side view, partly in section, of my automatic stop-motion.

In the drawings, a indicates the outer end of the mule head frame; a, the quadrant-pinion; (0*, the drum on the shaft of the quadrantpinion; b, the quadrant-band; c, the changelever, and c the cam-plate, usually called the steeple.

In the normal operation of the mule the change-lever controls the clutch mechanism through which the carriages are operated and is operated by some part connected to the carriage or carriages, usually the faller-shaft.

The stop-motion consists of the plate d, secured to the frame a and provided with bearings for the rock-shaft d. The brackets 61 61 are secured to the rock-shaft cl and form the journal-bearings for the roller (1 The collar d is also secured to the rock-shaft d and is provided with the stop 01 The cylindrical case (1 is secured in the plate (Z and extends vertically above and below the same. The cap d is screwed to the upper end of the case d and is perforated for the passage of the rod (1 provided at its upper end with a suitable handhold. The rod (Z is secured at its lower end to the plunger (1, fitting the case d with a loose sliding fit. The plunger has the notch (Z forming a seat for the plunger to rest on the stop (1. A longitudinal groove in the plunger d into which the stop-pin (Z enters, holds the plunger against rotation in the case, and the spiral spring 61 is compressed between the plunger and the cap (F. To the end of the change-lever c the extension 0 is secured, so as to extend under the plunger (P.

I will now more fully describe the operation of my improved stop-motion for spinning-mnles. In the normal operation of the mule the opposite ends of the change-lever are depressed when the carriage approaches the end of its outward or inward traverse. Vhen noW the quadrant-band breaks, the roller (P, which is supported by the quad rantband, descends, and in rocking the rook-shaft (1 moves the stop (Z out of the notch (Z The plunger (1, by gravity and by the force of the spiral spring (Z descends and encounters the extension 0 of the change-lever and either holds this end of the change-lever in the depressed position or depresses it. In this positton the carriage driving-out clutch is disconnected, the driving-in clutch is connected, and the mule is automatically stopped. If the carriage is running out, the stop-motion end of the change-lever is raised and the driving-out clutch is connected. When now the stop-motion acts, the driving-out clutch is disconnected and the mule is stopped.

Having thus described m y invention, I claim as new and desire to secure by Letters Patent 1. In a spinning-mule, the combination between the quadrant-pinion and the changelever, of an extension on the change-lever, a spring-pressed plunger over the extension, a rock-shaft, a stop on the rock-shaft for supporting the plunger, and a roller pivoted in brackets extending from the rock-shaft and bearing on the quadrant-band, whereby, on the breaking of the band, the Weight of the roller turns the rock shaft to release the plunger, as described.

2. In a spinningmule, the combination with the quadrant-band and the extension 0 secured to one end of the change-lever, of the rock-shaft d, the brackets (7' d secured to the rock-shaft, the roller d j ournaled in'the brackets, the collar d on the rock-shaft, the stop 02 on the collar, the case d supported in the plate d secured to the frame a, the cap d on the case, the notched plunger (1 the spiral spring 01 and the rod d secured to the plunger, whereby the plunger may be drawn upward to compress the spiral spring, normally locked and held in the locked position until the quadrant-band breaks, as described.

-In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
